CHIMNEY STACK AND INSTALLATION METHOD OF CHIMNEY STACK
To provide a chimney stack allowing a shaft member such as a clock driving shaft to project outward without degrading durability of a main body membrane.SOLUTION: A chimney stack 1 comprises: a duct 2 to discharge exhaust gas; skeleton members 4 arranged in a way surrounding the duct 2; a first main body membrane 5a arranged on an outer side of the skeleton members 4; a second main body membrane 5b arranged on an outer side of the skeleton members 4 spaced apart from the first main body membrane 5a; tension means 19 applying tension to the first and second main body membranes 5a, 5b; a cut-off membrane 6 having a pair of membrane bodies 6aa, 6bb and sealing a space between the first main body membrane 5a and the second main body membrane 5b; and a shaft member 7 inserted in an insertion hole 62 configured to combine cutouts 30, 30 formed in each of the membrane bodies 6aa, 6bb of the cut-off membrane 6, being arranged over from an inner surface side to an outer surface side of the cut-off membrane 6.SELECTED DRAWING: Figure 3
【課題】本体膜の耐久性を低下させることなく、時計の駆動軸などの軸部材を外部へ突出させることができる煙突を提供すること。【解決手段】煙突１は、排ガスを排出させるダクト２と、ダクト２を囲むように配置された骨格部材４と、骨格部材４の外側に配置された第１本体膜５ａと、第１本体膜５ａから間隔をおいて骨格部材４の外側に配置された第２本体膜５ｂと、第１及び第２本体膜５ａ、５ｂに張力を付与する引張手段１９と、一対の膜体６ａａ、６ｂｂを有し、第１本体膜５ａ及び第２本体膜５ｂ間を塞ぐ止水膜６と、止水膜６の各膜体６ａａ、６ｂｂに形成された切欠き３０、３０を組み合わせて形成された挿通孔６２に挿通されて、止水膜６の内面側から外面側に亘って配置された軸部材７と、を備えている。【選択図】図３
